Avocado Toxicity

An owner called the hospital today and wanted to know if avocado is poisonous. Specifically, she wanted to know if avocado is poisonous to dogs.

Short answer - no. Dogs can eat quite a bit of avocado without problem. The pits are mainly a problem if they are swallowed whole and end up becoming and obstruction. Too much avocado = bad diarrhea.

Here's a quote from Dr. Mark Grossman:
Avocado does contain the toxin persin. The leaves, fruit, bark, and seeds contain the toxin. In dogs and cats however, it does not seem to be as much of a problem as in cattle, horse, goats, rabbits, birds and fish.
Signs including vomiting, diarrhea, death, inflammation of mammary glands of rabbits, goats, cattle, and horses are seen. As well as cardiac failure in goats with respiratory distress, generalized congestion, fluid accumulation around the heart.
A few cases of dogs becomming sick exist but they have to consume large amounts.


In other words - don't feed your goat avocado! Dogs - OK.

This has also come up because of a popular new food called Avoderm. Dasuquin also has avocado in it. It's OK. By all measurements, Avoderm appears to be a good food. Don't let the avocado part of it worry you.
